IMPROVEMENT IN LAMP-CHIMNEY HOLDERS.

Specification forming part of Letters Patent No. 148,144., dated March3, 1574; application filed September 20, 1873.

To all whom it may concern:

Be it known that I, HENRY T. SANFORD, of Nicholville, in the county ofSt. Lawrence and State of New York, have invented a new and ImprovedLamp-Chimney Support, of which the following is a specification:

The accompanying drawing represents a vertical central section through alamp burner and chimney, showing my improved chimneysupport.

The object of my invention is to so attach the chimneys to the burnersof coal-oil lamps in common use that their dropping off and breaking arefully prevented also the cracking of the same, caused by the pressure ofthe burner against the inside and outside of the chimney.

The lamp may be held in any position without droppingthe chimney, andtlie'supportin g device be easily adjusted to difl'erent sizes ofchimneys.

My invention consists in an arrangement of springs and hooked wires witha lamp-burner, for the purpose of holding glass chimneys securely, andthereby preventing the destruction of them, which is so frequentlyincident to most of the attaching devices heretofore used. The wires areretained in position and set to the sides of the chimney by screwingtheir lower ends through lugs of the burner, clasping thereby thechimney in connection with several springs on which the base of thechimney is supported. A solid band, encircling the burner around thebase of the chimney, secures a steady light, as no air can enter thechimney.

In the drawing, A represents the burner; B, the chimney; and G, thewires, passing up from the base A of the burner to the top of thechimney. The base A of burner A is pro vided with lugs a, which extendat opposite sides and under right angles to the wick-tube, and serve tosecure the threaded ends of wires 0 through the same. Wires 0 passthrough guide perforations of the lower perforated burner plate, the topplate being thereby firmly held in position. The upper ends of wires 0are bent, forming small hooks b, which take hold on the top of thechimney B and secure the same. Two or more band-springs, D, areappliedto the base A below lugs (1, extending radially over the bottom.plate, and are bent up at their ends to carry the base of the chimney,and retain it firmly together with wires 0.

The wires 0 do not in the least obstruct the light, and may belengthened or shortened by their screw ends, so as to suit longer orshorter chimneys.

A solid rim, (1, encircles the perforated burner-plate and the base ofthe chimney, and prevents thereby the admission of air under the base ofthe chimney, producing a steadier light and a more equal expansion andcontraction of the chimney, so that the same is protected from crackingtoo easily.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of burner A A, having supporting-lugsa and band-springs D, with wires 0 and chimney B, to securely retain thelatter, substantially as shown and described.
